Patent JP-H02137373-A (JP)
Title: Manufacture of semiconductor device
Inventor: SAITO SHUICHI
IPC: H01L29/786
Filed: 1988-11-18
Abstract: PURPOSE:To restrain a dopant from being diffused to the side of a channel from a source-drain and to form a high-concentration impurity region with good controllability by a method wherein, after one part of a region to form the source-drain has been removed, doped amorphous silicon is filled, deposited and crystallized. CONSTITUTION:Only a region, to be used as a source-drain, of an SOI film 3 is etched; a spontaneous oxide film is removed; a clean silicon face is exposed; after that, amorphous silicon 9 whose n-type has been doped with arsenic and whose p-type has been doped with boron is filled and deposited. Then, this assembly is heat-treated in an identical vacuum; after that, it is moved to an electric furnace and is annealed; then, a single-crystal silicon 10 is grown in a region to be used as a sourcedrain. Other regions become polycrystalline silicon; the polycrystalline silicon is removed selectively. Since a heat-treatment temperature is low during this process, a dopant is not diffused. Thereby, it is possible to form the source-drain where an impurity is not diffused (especially in a transverse direction).

Title: Distance detector
Inventor: MURAKAMI FUMIO
IPC: G01S7/48
Filed: 1990-10-31
Abstract: PURPOSE:To enable highly accurate distance measurement even in the case of rapid change in the distance of the object or reflectivity by varying light casting signal level rapidly and keeping a receiving light signal level constant. CONSTITUTION:A control signal 21 is calculated with an arithmetic circuit 19 from the receiving light level signal detected by an amplitude detection circuit 14. With the control signal 21, the amplitude variation circuit 23 inserted between a signal generator 1 and a light source 2 is controlled and the amplitude of modulated signal impressed on the light source 2 is varied. Assuming the dynamic range of the receiving light of a distance detection circuit 13 to be X decibel and that of a reference signal to be Y decibel, this device enables the measurement of (X+Y) decibel range of reflection fraction variation from the object. And the time necessary for varying the light casting signal level in correspondence with the reflection fraction variation is the sum of the response time of the magnitude detection circuit 14, calculation time of an arithmetic circuit 19 and the response time of the amplitude variation circuit 23 (below a few millisecond) and so very rapid function is enabled.

IPC: H04N19/60
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To provide a moving picture encoder and decoder that generates no excess picture causing deterioration to image quality such as a pattern in padding of a referenced picture before motion compensation. SOLUTION: A padding circuit 16b of the image encoder 10 reads a macro lock including an object border from a VOP memory 16a as a reference image. The padding circuit 16b obtains a mean vale of pixels in the object of this block ad supplies this mean value to pixels at the outside of the object. A motion vector detection circuit 16c detects a motion vector of the current image on the basis of the supplied reference image and a motion correction circuit 16e properly corrects the motion b using the motion vector detected by this reference image and gives the result to a sbtractor 22. The sbtractor 22 tales the difference between the current image and the reference image. A texture encoding circuit 14 encodes an image signal resulting from the difference to suppress deterioration in the image quality.

Title: Printing head control device
Inventor: SUEYOSHI KENICHI
IPC: B41J29/38
Filed: 1986-12-10
Abstract: PURPOSE:To prevent deterioration in follow-up performance or duplication capabilities by prolonging an energization time for a printing head at lower temperatures than a thermal protection operating temperature. CONSTITUTION:A first operating point A on a high temperature side and a second operating point B on a low temperature side are detected respectively by means of resistance variations following an increase in thermister temperatures. A thermal protection circuit 13 operates at the time when the first operating point has been detected, applying thermal protection to the action of a printing head. A printing head drive control circuit 14 operates when the second operating point has been detected to prolong an energization time for the printing head. Consequently, a faulty follow-up action or deterioration of copying capability due to a decrease in printing pressure at the time of temperature of the printing head being risen is prevented. At the same time, the degradation of the printing head also can be prevented because of the shortening of a time in which the printing head is exposed to a high temperature area.
